PATRICK H. MONTAGUE, OF ST. LOUIS, MISSOURI.

WAREHOUSE-TRUCK.

SPECIFICATION forming part of Letters Patent No. 262,813, dated August15, 1882.

Application filed June 28, 1882.

To all whom it may concern:

Be it known that I, PATRICK H. MONTAGUE, of t he city of St. Louis, inthe State ofMissouri, have invented a certain new and useful Im- ])lovement in \Varehouse-Trucks, of which the followingis a specification,reference being had to the accompanying drawings, formingpart of thesame.

My improvementrelates to the class of trucks that are made capable oflifting their load after it is placed upon them. It consists mainly inpivoting the floor of the truck at its edges to segmental bars that aremade to roll upon the floor to raise and lower the truck-top. Thesesegmental bearin gor fulcrum bars are operated by levers or handles.They have upon the end opposite to the trunnions upon which the trucktopis supported wheels that are used to support the truck when wheeling itfrom place to place. Beneath the truck-top is a frame that prevents thetilting of the top upon the trunnions.

In the drawings, Figure 1 is a side view, showing the top elevated. Fig.2 is a top view. Fig. 3 is a side view with the top in its lowerposition. Fig. 4 is a rear end view with the top raised. Fig. 5 is a topview of the truck-top with the turn-table removed. Fig. 6 is alongitudinal section of the top, showing a tilting turn-table thereon.Fig. 7 is a transverse section of the top, showing a side view of theturn-table in its tilted position. Fig.8 is an under perspective view ofthe wheel-plate that is attached to the bottom of the turn-table. Fig. 9is a top perspective view of the pivot-plate that the table turns on.

A A are the segments to whose ends the top B is connected by trunnionsB, projecting from the top at or near its middle. At the opposite endsof the segments are the supporting-wheels G of the truck, turning on anaxle, D, that extends from segment to segment and serves to brace themtogether.

E are the handles through which the axle passes, the handles beingadjustable by turning on the axle, and being held in position by a bolt,F, passing through the handle and into the segment.

It will be seen by examination of Figs. 3 and 1 that when the top isdown the wheels are elevated, and vice versa. I prefer to make the rearend of the top a little longerthan the fore (No model.)

end, and prefer to bevel it, as shown,to aid in the rolling of a barrelupon the top when in its depressed position. Beneath the rear'corners ofthe top are rollers G.

H and I are dependent or foldinglegs, have ing pivotal connection attheir upper ends to the edges of the top B. These legs are connectedtogether by side rods, K, each side rod serving to connect the fore tothe rear leg up-' on the same side, so that they move togethersimultaneously in rising and falling. The rear legs, I, may be connectedto the segments by rods shown by dotted lines at L, Fig. 1, thearrangement being such that as the top rises from the position shown inFig. 3 the legs H and I gradually assume a vertical position, (see Fig.1,) so as to prevent the tilting of the top B upon the trunnions B. Atthe lower ends of the legs H are books E, that engage the axle D as thewheels 0 reach their lower position and the top B its upper position,(see Fig. 1,) and prevent the backward tilting of the top. Above thehook is a curved guide, H that receives the pressure of the axle D andassists in the movement of the legs as they are attaining a verticalposition.

This truck may be converted into a common two-wheel truck by making thehandles loose on the axle by the removal of the bolts F, thetruckbeinginthepositionshowninFig.3. The segments are then swung overuntil the wheels touch the floor. The rods I having been first removed,the ends of the handles are dropped upon the floor at the front of thetruck, and the handles are then connected to the segments, so that whenthey are raised the top will be lifted with them and the truckmay bewheeled around upon the wheels, the segments being then out of useexcept as side arms serving, with the levers, to support the top.

In Figs. 5 to 9, inclusive, I show atilting turn-table connection orattachment. M is a pivot-plate attached to the top B, and having acentral pivot, N, that enters a recess, 1?, in the turn-plate 0. Theturn-plate O is attached to the under side of the turn-table 1%. Uponthe pivot-plate M are longitudinal ribs M, and in the under side of theturn-plate are grooves O, fitting on the ribs M when the turn-table isstraight with the truck, as shown in Fig. 5. When the turn-table isin aposition transverse to the truck, as shown in Fig. 6, the flat part ofthe plate 0 rides upon the longitudinal ribs M, and may be tiltedsidewise upon them, as shown in Fig. 6, to make unloading more easy.\Vheels or solid segments may be used in place of the segment-bars A.

Wheels may be put upon the lower ends of legs I.

I claim 1. In a truck, a top or table having pivotal connection tosegments upon each side, substantially as set forth, in combination withsupporting-Wheels O.

2. The combination of top or table B With pivots or trunnions B,engaging in the segmental bars A, handles or levers E, and wheels G,substantially as set forth.

3. The combination, with the top 13 and segments A, of the pivoted legsH I, substantially as and for the purpose set forth.

allowits tilting when in its transverse position, 0

substantially as set forth.
